How do you view sex?
I'm not particularly sure how to answer this.
I view sex as a pleasurable way for people to bond.
I don't feel people should be married before they have sex but I don't believe in casual sex. Spiritually, I feel that when you have sex you open your base chakra up and connect with another person that way. This gives that other person a direct connection to you spiritually. I wouldn't want to open myself up to someone who would abuse that connection.
That's probably how I will explain it to my children when I have them.
